Do you have a question about the Ellipse/Circle Jig and is the answer not in the manual?

The ellipse jig does not match the Bosch router and the process of having to field modify the jig is not a pleasant task. The material chips when drilling and interference with existing holes can occur in the process. The fact that the jig was not predrilled for use with the popular Bosch router is very disappointing.
